Introduction

This portfolio comprises a sampling of maps created during a six-week module, “Spatial Analysis,” at the Harvard Graduate School of Design in the fall of 2021. Each map highlights a skill, or skills, that demonstrate proficiency in analyzing and mapping geospatial data in R.

Displaying Multiple Vector Layers

This map demonstrates the following skills:

  • Displaying multiple vector layers on the same map
  • Load spatial datasets from a file
  • Load a basemap image from the rosm package, using the ggspatial package
